Highly effective long-term light stabilization via regenerative nitroxyl radical mechanism.
Excellent compatibility with polyolefins, engineering plastics, and thermoplastic elastomers.
Low volatility and high thermal stability—suitable for high-temperature processing up to 300 °C.
Non-discoloring and non-migrating—preserves clarity and surface integrity in demanding applications.
Synergistic performance when combined with UV absorbers (e.g., Tinuvin 326/327) or phosphites.
Polypropylene (PP) automotive interior parts—including dashboards, trim, and seat components.
HDPE and LDPE agricultural films requiring extended outdoor durability and UV resistance.
Outdoor furniture and garden products made from injection-molded or extruded polyolefins.
Coated textiles, geotextiles, and synthetic turf fibers exposed to intense sunlight and weathering.
Thin-walled packaging and technical profiles where long-term color retention is critical.
